摘要
本文提出了基于AD7745构成的电容传感器阵列进行烟箱缺条检测的系统。系统由一个主单片机C8051F020,多个从单片机C8051F310构成。主从单片机间采用SPI总线通讯。从单片机与AD7745通过SMBUS连接。测量结果表明,系统检测效果可靠,具有很好的应用前景。
A detection system of a shortage in tobacco box based on capacitive sensor array using AD7745 is proposed in this paper. The system consists of a master MCU C8051F020 and some slave MCUs C8051F310. The master and slave MCUs are communicated bv SPI bus. The slave MCU is connected to AD7745 through SMBUS. Measurement results show that the detection effect of system is reliable.
